Take a look at these two online form builders. You want a form that visitors can fill in on their contact page? And then email you? Just use one of these online form builders, and either copy and paste the code into your own HTML page, or simply insert a link. They are pretty easy, just drag-and-drop modules, and if you get stuck, you can search for how-to video tutorials on Youtube. Go get!
Jotform is tried and trusted, and it's free, unlimited forms. Wuform is new and groovy, but only three free forms. But hey, you won't use more than three, right?
